Application filed December 26, 1917. Serial No. 208,890.

To all whom it may concern:

Be it known .that I, WILLIAM J. BURKE, a citizen of the United States, residing at an Francisco, in the county of San Francisco and State of California, have invented a new and useful Wind-Shield Cleaner, of which the following is a specification. 7

It is'the object of this invention to provide anovel means for imparting a continuous reciprocating movement to a pane-wiper, and to improve and to enhance the utility of devices of that type to which the present invention appertains.

One form only of the invention is shown in the drawings, and changes fallin within the skill of a mechanic may be made without departing from the spiritof the invention.

In the drawings:

Figure 1 shows in elevation, a wind shield to which the present invention has been Flg. 2 is an end elevation wherein parts are broken away; I

Fig. 3 is a section on the line 33 of Fig. 1.

, Although the structure hereinafter described may be used in many different ways, it has been shown in connection with the wind shield of an automobile, comprising a frame 1, carrying a transparent ane 2. A depending bearing 3 is attached y a screw 4 or otherwise to the top portion of the frame 1. A casing 5 is provided, the same having an arm 6 held by a set screw 7 if preferred, to the side portion of the frame 1.

A vertical shaft 8 is journaledin the easing 5 and may be flexible. The shaft 8 may be-driven from some part of the speedometer mechanism, but it is essential that some suitable means be provided for rotating the shaft 8 continuously in one direction.

The numeral 9 marks a horizontal drive shaft having oppositely wound threads 10 which communicate at their ends asshown at 11. The numeral 12 denotes a rider ineluding a sleeve 14 mounted to slide on the tudinally of the shaft 9,

shaft 9 and having an internal projection 15 adapted to engage the'threads 10, one at a time. A head 16 is carried by the sleeve 14 and holds a wiper 17 adapted to engage the pane 2. Any suitable means may be employed for operatively connecting the shafts 9 and 8. As delineated, intermeshing beveled pinions 18 on the shafts are employed for this purpose.

When the shaft 9 is rotated by means of the shaft 8, continuously in one direction, the rider 12 moves in one direction longiand then moves back in an opposite direction, the projec tion 15 on the sleeve 14 coacting first withone of the threads 10, and then with the other of the threads.

What is claimed is:

The combination of a depending bearing adapted to be suspended from the top rail of a wind shield frame; an arm; means for securing one end of the arm removably to one side portion of a shield frame; a gear casing adapted to be supported from the side rail-of a shield frame; a revoluble double threaded shaft having one end journaled in the bearing and adapted tov be positioned below the top rail of a shield frame, the

other end of the shaft extending into the casing, the shaft having oppositely inclined threads communicating at their ends; a sleeve slidable on the shaft and having means for engaging the threads; a panewiper mounted on the sleeve and adapted to contact with a pane, the wiper extending upwardly above and downwardly below the shaft; a second shaft journaled in the casing for rotating the first mentioned shaft; and gearing in the casing for connecting the shafts.

In testimony that-I claim the foregoing as my own, I have hereto affixed my signature in thepresenee of two witnesses.

WILLIAM J. BURKE.
